Application filed October 16:1922. Serial No. 594,781.

To all whom it may concern:

Be it known that I, J osnrn Soss, a citizen of the United States, andresiding at Brooklyn, in the county of Kings and State of New'York, haveinvented certain new and useful Imgovements in Methods of Manufacturinginge Butts, of which the following is a specification, such as willenable those skilled in the art to which it appertains 1.0 to make anduse the same.

This'invention relates to hinge butts, and

The invention is fully disclosed in the following specification of whichthe accompanying drawing forms apart in which the of my improvement aredesignated 'by suitable reference characters in each of the views, andin which Fig. 1 is a plan view of a hinge butt made according to myinvention- Fig. 2' is a partial section on the line 22 of Fig. 1.

' Fig. 3 is a perspective view' of one of the hinge butts shown in Fig.1 made according to my improved method.

Fi 4 is a plan view of one blank from whic my improved hinge butt isformed.

Fi 5 is a side edge view showing the first step 1n fashioning the blankshown in Fig. 4.

Fig. 6 is a section on'the line 6-6 of 4 Fig. 5 showing another step inthe formation of the blank shown in Fig. 4.

Fig. 7 is a view similar to Fig. 5 and showingthe next step.

Fig. 8 is a perspective view of another blank from wh1ch my improvedhinge butt is formed.

Fig. 9 is a side edge view of the blank shown in Fig. 8 and showing thenext step in the operation of fashioning the same.

Fig. 10 is. a sectional view similar to Fig.

separate parts hinge butt as hereinafter 9 showing the next step in theoperation of fashiomn the blank shown in Fig. 8; and,

Fig. 11 1s a sectional view through both of the fashioned blanks shownin Figs. 7 and 10, asembled; and, i

Y F1g. 12 is a section on the line 1212 of Fig. 11 showing the last stepin forming my imlproved hinge butt.

11 Figs. 1 and 2 of the accompanying drawing, L have shown a completehinge e0 15 formed by separate hinge butts 16 and 17 ]O1I18d. togetherby a pivot pin 18 in the usual manner, but my invention relatesspecifically to the method of forming the hinge butt 16, and carrying myinvention into effect, I provide two sheet metal blanks 19 and 20 shownin Figs. 4 and 8 respectively, the blank 19 being composed ofcomparatively thin sheet metal, while the blank 20 1s composed ofheavier sheet metal, and is used as a filler for the blank 19 whenfashioned to the desired form, and the blank 19 forms a casing or jacketfor the filler formed from the blank 20.

The blank '19 is substantially elongated and rectangular in form and isprovided at the opposite sides thereof adjacent to the end portion 19thereof with lateral extensions 19 and said end of the blank is slightlycontracted as shown at 19, and in the production of a hinge butt, theblank 19 or the end portlon 19 thereof is first fashioned to form asubstantiallyhook-shaped end 19 having top and 'bottom integral andsubstantially circular plates or flanges 19 and in this step of theoperation, it will be noted that the drawn metal will be slightly raggedat its edges as indicated in Fig. 5.

The next step in fashioning the blank 19 consists in bending the sideedges of'the blank 19 inwardly to form flanges 19 as shown-in Fig. 6 ofthe drawing, and indicated in dotted'lines in Fig.5 of the drawing',after which the blank thus formed is placed in a finished forming die tocomplete 5 the proper formation of the blank 19, after which the taggededges are" trimmed as shown at 19 in Fig. 7 of thedrawing, and

the plates or flanges 19 are pierced or drilled to form apertures 19 toreceivethe 1 pivoted pin 18, and it will be noted that a slight shoulder19 is formed in the above finishing and trimming opera-tion.

The blank 20, from which the other part of my improved hinge butt isformed, is cut at the end portion 20 thereof to form two elongatedapertures 20" forming three projecting fingers or arms 20, the ends ofwhich are slightly curved and preferably rounded as shown at 20. Afterthe blank 20 has been formed in the manner above set out, and by the useof suitable dies, the finers or arms 20 thereof are fashioned to formsubstantially circular pin receiving knuckles 20 as shown in Fig. 9 ofthe drawing, after which the blank is broached as shown at 20' in Fig.10 of the drawing, and the formation thereof is completed to permit ofits insertion into and assemblage with the fashioned blank 19 shown inFig. 7 of the drawing.

The next step in forming my improved hinge butt consists in placing thecomplete blank 20 formed as shown in Fig. 10 within the complete blank19 shown in Fig. 7 of the drawin in the manner illustrated in Fig. 11.witi the knuckles 20 of the blank 20 within the hook-shaped portion 19of the blank 19, and the separate parts are pressed or fit together bythe use of suitable dies, after which said parts are welded or otherwisesecured together, as shown at 21 in Fig. 11 of the drawing, and thescrew holes or apertures 22 are punched or drilled therein andcountersunk as shown in Fig. 11.

It will be noted that the flanges 19 of the blank 19 project. slightlybeyond the face of the blank 20 as shown in Fig. 11 of the drawing, andin the finishing operation of the complete hinge butt, the projectingportions of the flanges 19 are pressed inwardly to lie flush with theface of the fashioned blank 20 as shown in Fig. 12, and this operationmay be performed before or after the parts have been welded or otherwisesecured together.

It will be-noted that the separate operations of forming the separateparts of my improved hinge butt as herein set out may e produced in oneor more operations in a suitable machine and by the use of suitable diesas for example, the substantially hookshaped portion of the blank 19.while being described as formed in a single'operation,

may be formed in one or more successive operations in order that themetal will not be strained or ruptured in accomplishing the desiredresult and as this is the common practise in the art of fashioning sheetmetal parts by the use of dies or other forming tools, it is not deemednecessary to specify the specific steps of the process, and while I haveshown a hinge butt of specific formation and design, it will be notedthat m invention is not necessarily limited in this respectand variouschanges in and modifications of the method of manufacturing hinge buttsherein shown and described, may be made within the scope of the appendedclaims without departing from the spirit of my invention or sacrificingits advantages.
